Product Description
MDO (Medium Density Overlay) Plywood — paint-grade, weather-resistant panels
Medium Density Overlay (MDO) is a paint-grade plywood with a weather-resistant resin overlay bonded by heat and pressure. The overlay contains at least 27% resin to resist water, weather, wear, and degradation while providing a smooth, paint-receptive surface with minimal grain appearance.
Available sizes & packaging
- 12" x 48" — sold individually
- 24" x 24" — sold individually
- 24" x 48" — sold in packs of 2 or 4
Specifications
- Overlay: resin-saturated paper face (≥27% resin)
- Face options: G1S (one side) or G2S (both sides)
- Thicknesses: 1/2" or 3/4"
- Paint performance: painted finishes on MDO are up to 3× more durable than the same finish on ordinary plywood
- Sold cut from 4' x 8' stock in our woodshop — allow approx. ±1/4" variance for cut size
Benefits
- Smooth, patch-free surface ideal for professional sign painting and graphics
- Superior weather and moisture resistance compared with ordinary plywood
- Paint adheres well and lasts longer — reduces repainting frequency
- Minimal visible grain for a clean, uniform finish
- Versatile and easy to work with: can be sawed, routed, drilled, shaped, or laminated
- Durable for exterior use when finished with exterior-grade primer and paint
Typical uses
- Painted signs, sign boards, and routed signage
- Exterior and interior signage for retail, municipal, and commercial applications
- Exterior applications such as under-laminate substrate or durable cladding (use recommended exterior finishes)
- Cabinets, displays, kiosks, and other painted millwork or shop fixtures
- DIY projects requiring a smooth, paint-ready panel
Handling & finishing notes
- Apply exterior-grade primer and paint for any outdoor application; proper finishing maximizes longevity.
- Cut with standard woodworking tools; expect ~1/4" cutting variance.
- Use G2S for two-sided finishing; G1S if only one finished face is required.
